WARP GUIDE FOR- COIv'IIBS.

Application filed November To all whom it may concern Be it known thatI. .ALONZO E. RHoAnns, a citizen of the United States, and a resident ofI-Iopedale, county of lVorcester. State of Massachusetts, have inventedan improvement in Warp Guides for Combs, of which the followingdescription, in connection'with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to metal warp guides such as are employed in thecombs of warpers and slashers.

The object of the invention is to provide a simple form of such warpguide so constructed that when a series of warp guides are in positionall of the dents will be exactly in line throughout and thus prevent thewarp threads from becoming crossed and insure that each warp threadshall be guided in precisely the same manner and in substantialparallelism.

The object of the invention is further to provide such a sheet metalwarp guide which shall be formed integral throughout of a single pieceof sheet metal.

These and other objects and features of the invention will appear morefully from the accompanying description and drawings and will beparticularly pointed out in the claim. I

In the drawings:

Fig. 1 is a transverse section of a portion of a comb showing one of thewarp guides embodying a preferred form of the invention in place.

Fig. 2 is a View in front elevation of the warp guide shown in Fig. 1.

Fig. 3 is a view in side elevation of the warp guide shown in Fig. 1looking at the opposite side.

Fig. 4 is a view in rear elevation same warp guide,

Fig. 5 is an enlarged top plan View of a series of warp guides aspositioned in the comb with the warp threads guided thereby.

The comb hereinillustrated in connection of the with a disclosure of thepresent invention is of a similar construction to that shown in my priorPatent 818,560, granted April 24, 1906, and as the general constructionof such combs is well known and familiar to those skilled in the art nodetailed description thereof is necessary. In that construction 9, 1923.Serial No. 673,702.

each warper guide presents a long bottom shank held between theexpansible spring" holding device 1 and a pair of dents which arearrangedparallel to and separated from each other both laterallyand foreand aft so I i that one dent is located well forward of the other in thedirection of travel of the warp.

In the construction of the present invention each warp guide comprises asingle bottom shank and a pair of warp dents but these warp dents arearranged not only parallel to each other but directly opposite to eachother so that when the warp guides are assembled in the series in thecomb all. of the dents are exactly in line and thus the action of eachdent in guiding the warp is precisely the same and all danger ofcrossing of the warp threads in the comb or further along in theirtravel is prevented and thus the accurate guidance of the entire sheetof warp threads is secured.

The warp guide of this invention is formed entirely of a single integralpiece of sheet metal. Thus thewarp guide may readily be punched out andbent into the required shape requiring no soldering, welding or otheradditional operations and requiring no additional features ofconstruction in order to enable it satisfactorilyand efficiently toperform its functions.

In the construction illustrated as an embodiment of a preferred form ofthe invention the warp guide comprises a flat shank 2 and a flat dent 3forming a prolongation of the shank and lying in the plane of the shank.A second flat dent t is of the same shape as the dent 3 but is laterallyoffset from the first dent. The two dents have their flat faces paralleland are disposed exactly opposite to each other, or in other words,thecentral longitudinal axes of the dents both lie in a plane normal to thesaid faces. A. substantially semi-cylindrical portion 5 of the sheetmetal from which the warp guide is formed connects'the upper end of theshank 2 with the lower end of the dent 4. The axis 6 of thissemi-cylindrical portion 5 extends parallel to and midway between thedents. This semi-cylindrical portion merges the upper end of the shank 2into the dent 4.

In the construction of the guide theentire device is first stamped orpunched out of sheet metal while in a flat condition. The portionforming the dent 4c is then bent into parallelism with the dent 3 thusforming the semi-cylindrical portion 5 which unites the dent 4t with theshank 2.

The upper edge 7 of the semi-cylindrical portion 5 forms asmooth bridgebet-ween the two dents at their bases and prevents any danger of thewarp threads from being caught or pinched between the dents,

\Vhen the dents thusmade are assembled in the comb they standin acontinuous series directly in line as shown by the plan view in Fig. 5,and each acts to guid'ethe threads 8 in the same manner. Thus any dangerof the Warp threads being crossed between the different dents or duringtheir onward travel is prevented and the accurate guidance of the warpthreads is insured.

,Theconstruction of the warp guide is ex tremely'- simple and" is onewhich can be readilyga'nd' easily manufactured. There is no danger ofthe warp, threads being caught, worri'orchafeid by any portion of thewarp guide and there is no danger of separation of the one dent from theother.v I

Having thus described theinventiomwhat is claimed as new and desired tobe secured by Letters Patent, is:

As a new article of tegral, one piece sheet metal warp guide comprisinga flat shank, a flat dent forming a prolongation of the shank, a secondsimilar flat dent laterally offset from the first dent, the two dentshaving their flat faces parallel with the central longitudinal, axes ofthe dents lying in a plane normal to the said faces, and a substantiallysemi-cylindrical portion having its axis parallel to and midway betweensaid dents andmerging the up; per end of the shank into the lower end ofthe second dent. V In testimony whereof, I have signed my name to thlsspeclficatlon.
